TO ALL WHOM IT MAY CONCERN: i r I Bait known that I, DAVID Cox, of Troy, in the county of Bensselaer, end State of 'New' 'York, have invented an Improvement in Heating-Stoves and I do hereby declare that the following is a. full and exact description thereof, reference being bad to the accompanying drawings, making part of this specifieation Figure 1 being a top'view of the extension-ring in which my improvement consists.

Figure 2, a central vertical section representingthe principal parts of a stove, with the extension-ring applied thereto.

Figure 3,11 view of a stove provided with the extension-ring applied thereto.

Like letters designate corresponding parts in all of the figures.

My invention consists in an extension-ring,,A, to rest upon the bzise, B, of a. stove, and to receive'upon it the body or upper part 0 of the stove,being removable and replaceable at pleasure, in order to adapt stove. bodies of difi'erent sizes to one base, or to bases of one size, substantially as herein specified.

The mode by which the extension 'ing efiects thepurpose is illustrated in fig. 2. Let a represent the flange at the upper edge of the base, on which the body of the stove ordinarily fits. Then if it is desired to :ittach a.- body, 0, of larger size to thesame, or same-sized base 13, the extension-ring A is placed upon the base, and as the flange b of the ring is of larger diameter than the flange a of the base; it will receive a larger body, C, as .desired. Extension-rings of different sizes for one base may be used, to receive as many additional sizes of stove-bodies; and a. ringmay be applied in the some way, to diminish instead of increasing the size of the stove-body.

The ring-is made of cast iron, and may have any desired f01' m. and ornamentation.

What I claim as my invention and desire to secure by Letters Patent, iss An extension-ring, A, a pplicd between the base, B, and body C of a stove, substantially as and for the purpose herein specified. V p v The'above specification of my improvement in stoves signed by me, this twenty-sixth day of March, 1868.
